Ginger and Psoriasis: Skin Inflammation, TNF-α & Keratinocytes

Direct Answer: Ginger reduces anti-inflammatory-inflammation-natural-remedy">psoriatic inflammation through 4 mechanisms: TNF-α inhibition (central cytokine in ginger psoriasis), reduction of IL-17A and IL-23 (Th17 axis), inhibition of abnormal keratinocyte proliferation (epidermal anti-COX-2), and dermal NF-κB ↓. Systemic effect via internal consumption + potentially topical application. Complementary, not curative, approach.

Psoriasis: an autoimmune inflammatory disease

Psoriasis affects 2–3% of the Belgian population (200,000–250,000 people). It is a chronic inflammatory disease mediated by T lymphocytes (Th1/Th17 axis) with keratinocyte hyperproliferation. Biologics (anti-TNF, anti-IL-17, anti-IL-23) are effective but costly and reserved for severe forms. Ginger targets the same inflammatory pathways at a modest and systemic level.

Mechanisms of ginger in psoriasis

1. TNF-α Inhibition

TNF-α is one of the most important cytokines in psoriasis (anti-TNFs like adalimumab are very effective). Gingerols → dermal NF-κB ↓ → TNF-α↓ in keratinocytes and dermal fibroblasts. Reduction: −35 to −40% in in vitro models on human keratinocytes.

2. Reduction of the IL-17/IL-23 axis

The Th17 axis (IL-17A, IL-22, IL-23) is central to the pathogenesis of plaque psoriasis. Gingerols reduce IL-17 production by Th17 lymphocytes through inhibition of NF-κB activation in antigen-presenting dendritic cells.

3. Inhibition of keratinocyte proliferation

In psoriasis, keratinocytes proliferate 6–10× faster than in normal ginger skin. Intra-epidermal COX-2 contributes to this hyperproliferation. Gingerols → epidermal COX-2 ↓ → slowing down of abnormal keratinocyte turnover.

4. VEGF Reduction (anti-angiogenic)

Psoriatic plaques are highly vascularized (red, warm skin). VEGF↓ by gingerols → reduction of neovascularization → decrease in erythema.

INTI Protocol for Psoriasis

  • Internal Use: 2–3 INTI shots per day continuously (systemic approach)
  • Intensification during flare-ups: 3–4 shots/day, for the duration of the flare-up
  • Evaluation period: Minimum 12 weeks (psoriasis responds slowly to systemic interventions)
  • Anti-psoriasis synergies: Omega-3 EPA (arachidonic acid competition, anti-inflammatory PGE3), curcumin (IL-17↓, NF-κB↓), vitamin D3 (Th17 regulation), anti-inflammatory-science-utilisation">ginger anti-inflammatory diet
Psoriasis and Diet: Psoriasis is associated with increased intestinal permeability (leaky gut). Ginger improves the integrity of intestinal tight junctions (claudin-3, occludin↑) — addressing a mechanism often overlooked in psoriasis.

Frequently Asked Questions

Can ginger cure psoriasis?

No. Psoriasis is a chronic autoimmune disease with no current definitive cure. Ginger can reduce the intensity of flare-ups and improve the systemic inflammatory background, but does not eliminate the underlying immune cause.

Ginger and anti-TNF biologics (e.g., adalimumab): compatible?

In theory, yes — additive mechanisms and not in direct competition. No documented drug interactions. Inform your dermatologist for follow-up.

Topical application of ginger on plaques?

In vitro studies suggest a topical effect of ginger extracts on keratinocytes. Practically, diluted fresh ginger can be applied to plaques (test on a small area first — may irritate). No human topical clinical studies published.

Does psoriatic arthritis also benefit from ginger?

Yes, doubly so: joint anti-inflammatory (COX-2, IL-1β, MMP-3) + cutaneous anti-inflammatory (TNF-α↓, IL-17↓). Psoriatic arthritis shares pathways with rheumatoid arthritis where ginger is well documented.
